Renewed March 18 Claims.-

My invention relates to the lining of boxes, cartons, containers or the like, hereinafter generically termed boxes.

The better grade of wrapped. box is formed of cardboard, or other box material, which is lined,

of the box with paper, or like Heretofore, box .manufacturershave found it necessary to keep in stockvarious sizes of lined sheets whichare made by cutting cardboard she'etsto size, cutting lining paperto size, and delivering the cut sheets to a lining machine. To fill an order for boxes of a specified size, it was the proper number of lined sheetsfrom storage,

chines, then to corner-cutting machines,.the'reafter to staying machines, and eventually .to.

wrapping machines. In addition to the waste .oc casioned by trimming, many partially. formed boxes or blanks are rendered unfit'for use by injury received during the many transportation steps and operations involved. The method is expensive also because of the many machines and.

operators necessary.

In accordance with my invention, as a strip'of box material of exact width to form a box component, is removed, as from a roll, and more specifically, while it is being fed toward a fabricating station, as to the form-block structure of a wrapping machine, covering paper of the same or proper width removed from a roll of proper width is adhesively applied thereto; more particularly, cutting of the composite strip into pieces of proper length produces box components which may be delivered directly to'the fabricating station where, with complementary box com ponents similarly prepared they are arranged in box-forming position and permanently attached,

' as .by application-of wrappers, to form'" lined boxes. By this method, the wasteof material is greatly reduced; there is and thenumber of steps necessary to'form the boxes is materially lessened.

Further inaccordance with my invention, reinforcing strips are applied to a strip of box material before it is cut, and face to which the lining applied;

My invention further resides'in the methods and features hereinafter described and claimed.

For anunderstanding of my invention and illustration of some of the forms of boxes propaper is subsequently duced, reference is-to be had to the accompanying drawings in which in perspective:

Figs. 6 to 10 inclusive, illustrate-the successive steps of forming and. wrapping a lined compositebox.

Fig. 11 illustratesmodified forms. ofbox components- Referring to Fig. 1 the roll R of suitable box material, as cardboard, or the like, is continuously or intermittently rotated, and as the strip' isunrolled, engagement is effected with tapes t paper, withdrawn from Fresh adhesive is applied to the. tabbed strips, or adhesive thereon is moistened," by the rollers Gas the strips pass thereover prior to engagement with the strip of box material. Lining material,- as paper,- withdrawn from-the roll L,'is appliedto the surface of the strip of box material destined-to form the interior of the box, which in the example shown, is the same surface to which the tabbing-stripshave been previously-applied, the lining strip coveringthe tabbing. The tabbedlined-strip is cut as by the knives K1 to form boxcomponents C, each of which-as shown to the right of Fig. 1, comprises'a portion A adapted to form the bottom of r a boxand-portions or sections S adapted to'form oppositewalls, as said walls of a box. 7

Preferably before cutting of a blank from-the strip of box material, the strip is scored or I creased, asby knivesor rolls K to facilitate bend-.. 95 ing of the -blanks,.andzwhen the .tabbingis ape plied to the undersurface of the strip, the scoring. or creasing is necessarily effected prior :to the application of tabs.

As shown most clearly in Fig. 2, in which part 100 of the lining material is broken away, the tab strip t overlies the scoring or creasing to reenforce the inside corners of the box formed by the panels S andA.

Preferably each component C, as formed, is fed toward a wrapping station.- For example, the prepared component C, Fig. 2 is aligned with a wrapper W, Fig. 3, as shown in Fig. 4, and the assema bly thus formed is delivered to a wrapping station,

the rolls 1".

chine. The wrapper W, which is freshly coated with adhesive, is preferably tabbed, the tabbing being so disposed that when the panel A of the main component C is registered with the corresponding panel a of the wrapper, the tabs t1 thereon project in part beyond the edges of the main component as shown in Fig. 4.

During preparation of the main component,

minor components adapted for example, to form end walls of the box are being prepared in generally the same manner. Preferably adjacent the form block structure F, there are disposed rolls R1, of box material, on opposite sides of the form block. Sheet lining material fed from the rolls L1, is applied to the surfaces of. the box material strips destined to form the inside of the box, the rolls G2 supplying adhesive to, or moistening adhesive upon, the side of the lining strips contacting with the box material. The composite strips are cut as by the knives K2 to form end wall components E, E.

The feeding of the rolls R1, and operation of knives K2, is preferably timed with respect to the feeding of roll R and the cutting of components C therefrom, so that groups of components, each group comprising a main com-- ponent C anda pair of end components E are delivered in succession to the wrapping station.

Referring to Fig. 5, the lined end wall components E, E are swung into position registering with opposite ends of the form block structure F, the lined surfaces of the components being in contact with the blank. They are held in position by suitable means forming no part of the present invention. The assembly of Fig. 4 comprising the main component C and wrapper W adhering thereto, is brought for example, into the path of movement of the form block structure F, so that upon descent of the form block, the end components E are brought into box-forming position with the main component C.

During the wrapping operation, side panels s of the wrapper are brought into adhesive engagement with the unlined surfaces of side panels S of component C, Fig. 7, the corner lap portions ,f of the side panels 8 subsequently folded into adhesive engagement with the end wall components E, E, Fig. 8, the tab structure 151 overlying the vertical corners of the box formed by the components E and C. Subsequently the end panels e are folded upwardly into adhesive engagement with the end wall components E, the central portion of the tab structure t1 overlying the lower end corners of the box formed by the end wall components E and the bottom A of the box, Fig. 9.

Thereafter, the portions m of the wrapper, projecting beyond the top of the box are folded over the top edge and downwardly into engagement with the interior of the box, or more specifically, the lined surface of the components E and C.

As shown in Fig. 11, the lining material need not completely cover the surface of the components C and E, forming the interior of the box, but may terminate short of the edges of the components forming the top edge of the box, leaving an exposed or uncovered portion M which however, is covered by the marginal turn-in portions m of the wrapper during the wrapping operation, these turn-in portions completing the lining of the box material. The advantages are two-fold, as the width of the rolls L and R1 of lining material may be correspondingly less, and the coarser surface of the box material is superior to the relatively smooth surface of the lining material for receiving the adhesive upon the marginal turn-in portions m of the wrapper.

While one group of components is being wrapped, one or more other groups are in course of preparation, so that the method is continuous with no storage of components which would involve transportation and repeated handling.

While all of the steps may be performed manually, at least many of them may be effected mechanically. For example, the feeding of the box component and wrapper assembly of Fig. 4, to the form block structure F, the cutting of the end wall box components from continuous strip material and feeding of end components so cut to the form block structure, and the uniting of the components in box-forming position during a wrapping operation, can be effected by a box machine similar, for example, to that of copending Rider application, Serial No. 460,859, filed June 13, 1930.
